Expression of forkhead box (Fox) mRNA in pleural fluid mononuclear cells (PFMC) and interleukin (IL)-8+ FoxP3+ Treg. FoxP3 mRNA levels in peripheral blood mononuclear cells (PBMC) and PFMC of HIV/tuberculosis (TB) patients assessed by real-time polymerase chain reaction (PCR) are shown in (a). FoxP3 mRNA was significantly higher in PFMC compared to PBMC (P < 0·002). In (b), IL-8 expression in FoxP3+ T cells is compared between CD4+CD25hiT cells [regulatory T cells (Treg)] and CD4+CD25lo and CD4+CD25- T cells. Intracellular IL-8 was significantly higher in Treg than the other two populations (P < 0·05 and < 0·001, respectively).
